Ordered 3 chargers off of ebay, none work

Ordered a universal one with wall attachment and car attachment and when I connect the USB to microUSB cord the phone doesn't charge. Ordered another stand alone car charger and it, also, doesn't charge. If I attach the USB cord that came with the phone to the wall/car charger it charges fine. Both, specifically said for the "Nexus One". Is it an amp issue? Most microUSB charger in the mall cell phone kiosks won't charge it either. Is it a proprietary microUSB cord that I need or a matter of amps or something?

Why not buy from Monoprice.com?!
I ordered 8 USB cords (2/each of 4 different lengths), 2 Car Chargers, and 2 Wall chargers. All work perfectly fine, and I paid under $25. (Wife has a CLIQ, so we got plenty to work for both of us.)
So, I don't know what your issue is... Other than just not going to Monoprice

well I havent ordered from monoprice since customers got slammed with bogus charges... i guess i could give them another try though, but still... kinda weary

Why? I had over $1300 attempted to be spent at Newegg, and my CC company called me and stopped the charges. Got a new CC in the mail the following day. Some random amount at Apple as well. LOL. Fun times.
(Yes, it happened to me. I'm fairly confident it was from the same issue as others..) But, that doesn't stop me from using a company that makes good products, expecially when they just made such a big mistake. Odds are, it won't be happening again for a long while
Either way... Those are risks with online shopping. You just have to make sure that your method of purchase has fail-safes.

I have a CRAP load of mini USB chargers (all HTC stock) and didn't want to buy more. I bought a bunch of Motorola mini to micro adapters off Overstock.com for $2 a piece and couldn't be happier. I also bought the official Google cradle to avoid additional wear and tear on the microUSB port.

I bought a car/home charger from eBay when I had my Motorola Cliq, and my home charger would keep going on/off charging. I later found out that it was the voltage issue, where the charger was giving a maximum of 5 amps and the Motorola Cliq needed 5.1V or something like that.

But most chargers I've bought don't power the Nexus One. What specific voltage or amps should I look for it to have? The two I bought off of eBay specifically said they were for the Nexus One. Neither worked. Sellers are putting any micro SD chargers up for sale assuming they will change the phone. They will not. What technical spec will tell me if it really will charge it?

Could someone post a link to a USB charger that absolutely works? I just bought another one from Best Buy that doesn't charge the Nexus. Made by Rocketfish and is suppose to be universal.

Thats really wierd. Every charger i've tried works fine.
You're charger should be outputting 5V and anywhere from 300mA upwards. There is no max mA limit because the phone will only draw what it needs.
This might sound patronising, and I really dont mean it to, but when you say doesnt charge how do you know?
Do you mean from totally flat it won't turn the phone on and start charging it, or do you mean when the phone is on the battery indicator doesnt show a charging, and the LED doesnt go orange/green?
Or do you mean it never charges to full?

When I plug it in it's as if nothing happens. No light, no thunderbolt symbol on the battery, no screen wake-up, nothing. Nada. Now, the HTC wall charger and usb charger work fine. But if a MicroUSB charger calls itself "universal" it does not mean it will charge the Nexus. The HTC HD2 charger my wife has works fine on the Nexus though.

Hmm strange.
The charge process works like this:
- Charger plugged in causes voltage change on +ve USB line - potential charger detected.
- Phone draws minimal current (50 to 100mA) and tries to negotiate USB power
-- If that suceeds it tries to increase power to 500mA if the USB port supports it. If yes charging starts at 500mA, if not charging starts at 100mA
- If USB negotiation fails, it checks if D+/D- are bridged.
-- If D+/D- are bridged, the phone draws as much current as it can/needs
-- If D+/D- are not bridged, the phone draws a max of 500mA
There's nothing special about the chargers unless they have been wired in some special way for a specific phone. Thats why I'm very surprised these chargers dont work.
I know that if I chop a USB extention cable and cut out D+/D-, my nexus charges at 500mA. I've tried this myself for a totally different purpose. Thats no different to ground and power being wired to a 5v source.

Odd, I have three car USB adaptors and two AC USB adaptors.. All charged the phone, although only the AC charger shipped with the Nexus would do a fast charge, and none of my car chargers would. I found one that was rated 1Ah and soldered the two middle pins, now it works as a fast charger too.

The Motorola P513 car charger (OEM designed for a Droid) gives out 950mA, is super cheap (~$3+shipping), and works great for a fast charge with the Nexus One.

Thank you sir. I've been trying to find a car charger that guarantees a fast charge.
Just ordered one from Play.com for £3.99 w/ free shipping.
Maybe now I can use GPS for more than an hour...

I dunno.
My motorola charger for my old bluetooth (H780?) works fine, as well as the original google charger. I also have a car charger for my old bluetooth as well.
My suggestion, is to only buy name brand chargers?

900mA mini car adapters with USB port(s)

http://www.amazon.com/Powerjolt-Dual-Universal-USB-Micro/dp/B0042B9U8Q/ref=pd_cp_e_1
Anyone know if there are any devices like this that has 900mA output (or know what output the linked one has)? Seems that's the minimum needed to charge the Charge via USB. My current one rated at 700mA does nothing when plugged in the Charge.

My friend has one something like this and I was using it for my Charge and it worked fairly well. I am not sure if it is the same one but they look the same size, I just used the usb that came with the charge to plug into it and it worked. It also works well with his iphone 4 if that helps at all.

$1.99 free ship, takes a while because it comes from china, but worth the wait it is 1000ma like the wall charger.

Do you actually own this? I'm pretty interested in it as mine has stopped working.

I came from the fascinate and the wall charger was only 0.7A and the Charge wall charger is 1.0A
I was looking at some brands and found a Belkin Micro Charger for the car that charges at 2.1A (Says rapid charge)
Checked around for any other products and found this at newegg. $9.99 2.1A USB charger.

Edit: Also found this on ebay. knockoff no name. Looks the same as a scosche one I found.

IDK....I'll find out I guess...I ordered it.

I just ordered 2 off of eBay. Will see how they work.

http://www.amazon.com/gp/product/B00470C35E
I ordered this one, if it doesn't work or isn't small enough I will prob try the $2 one from eBay. Thanks for all the suggestions.

I bought a dual usb car charger (it has 2 usb ports) that says its for ipads or tablets, and supplies 2A. It does seem to charge faster than my other car chargers, but I think it also triggers USB mass storage mode, because apps stored on the SD card aren't usable when its plugged into this. Is this because of the USB cable i'm using (a generic USB to micro usb cable)? or is it because of the charger?
this is the charger - although Amazon's pictures don't exactly match - the one customer supplied picture does, though.

I'm not interested in the usb plug kind. I'm looking for wall and car chargers that aren't usb and just charge (hope that makes sense).
Thanks.

Nexus 4 car charger??

Hi
Im searching for a car charger for the nexus 4 that will charge the device even on navigation running...I now that the Motorola Rapid car charger was good with the galaxy nexus.I dont know if itS ok with the nexus 4 because on the LG charger it sayS 1.2A?I read that the Bracketron Universal Dual USB Car Adapte 2.1A will just work as AC charger if plugged in with a USB charging only cable...but i cant find those cable to order online here i Canada...and i dont wanna do it myself and modify a regular usb cable ...Soo if someone can help me it would be much appreciated.

You dont have to have a modded cable if your car charger already has the data pins shorted. Im using the motorola rapid charger too and it works fine, it will charge your phone as AC and give enough power to recharge the battery with navigation on. if you want something a bit better you can try this one , they ship to canada. My rapid charger broke so i bought it a few days ago. Reviews says the trident will give around 8-900mA, the moto charger outputs around 6-700mA.

I would only buy a premium brand here. If you see how no name mains adaptors are made... the risk of blowing up something expensive is just too big.
I wnent with the Sony AN-400 / 401, because it is rated at 1.2 amps exactly, is small, and was reported to work fine.
For some regulator disasters:
http://hackaday.com/2012/08/15/buying-cheaper-electronics-and-not-saving-money/ <- a USB car charger without components, putting 12 volts straight on USB.
http://www.youtube.com/watch?v=wi-b9k-0KfE <- teardown of imitation apple mains adapter, showing no output protection and very little gap between mains voltage and output circuit. Good info, but style of presentation is not my cup of tea.
So that is why I went with a premium brand.

that's one charger from one factory that some guy that didnt know what he was doing and ordered thousands, without testing them. He probably went for the 25 cent super deluxe model...
Well reviewed chargers from xda members here and not to mention the hundreds of people on amazon are a safe bet. Here's a 8+page thread on the charger i linked. Your premium brand name sony charger is made in china too.

That looks ok,but I cant find a good quality usb charge only cable that ships to canada :

I have a el cheapo usb charger from ebay and I used my usb cable that came with the phone...and when i pluged it in it switches from AC charge to USB ever couple of seconds back and forth...so I want to try something different.

If you're into rooting and custom kernels, most of them have a fastcharge option where you don't need to have a special usb cable, or, attempt to short the D- and D+ lines.
Monoprice has a 2.1A bullet charger for a bit cheaper:

i cant say for sure until i get it sometime next week but i think so. im in canada too and couldnt find the powergen anywhere that would ship here.
There are some other brands that are good too but i like this one cause it's dual usb like my old moto rapid charger. If you dont need that you can get some smaller ones that will work just make sure they are well review and can output around 1A. The one that bfspider spider recommends is a good bet too since monoprice is pretty reputable store and will ship to canada.

You can try to mod this one in the mean time, just take it apart and attach the two data pins(they are the two middle ones). Solder is best but if you cant you can just use pilers and bend the pins until they touch. i did this with a few of my chargers too and it works to make them AC but it wont increase the output if its low to begin with.

FYI, this adapter should allow most existing "iPad" chargers (1.2A or higher) + any USB cable to work well with the Nexus 4.
The problem is that Apple products deviate from USB charging standards. As a result, most chargers try to be compatible with iDevices and also deviate from the standards. So when standard-compliant devices try to follow the standards, the chargers refuse to follow the standards, and the devices get upset with each other. Fortunately, they fall back and settle on a lower-power charging rate.
If you want to buy chargers that are very clear on what they support, check out MediaBridge (also available on Amazon).

Why does a bog standard USB cable work in the car for me? Using a proper off-line sat nav my phone was fully charged

So i got that Trident charger that you recommended....the quality looks good...but when I tried it in the 1A and 2A port with the usb cable that comes with it,it shows USB charging but when I use the HTC usb cable that came with my HTC one S it shows AC charging....its so confusing and I just dont get it....that HTC cable is a sync and charge cable.

The generic T-Mobile car charger available at T-Mobile stores charges just fine. I believe it is at least 1 amp. Its black, has a purple white small led indicator when charging. The USB end looks like a little block and the cord is an accordion type and it also has a a female USB slot in it to plug something else in at the same time but I believe whatever USB cord you plug in there only charges at .5 amp. With this charger I can run navigation and Bluetooth and Pandora and message at the same time and it will charge.
Sent from my often RMA'd Nexus 4, So that I can use the one I'm using now when I get the 6th and hopefully final one.

I just dont get it why does it with one cable show USB charging and with the other HTC cable AC charging?:S

the original charger has a dual mode operation, if you stick a regular usb cable it will work as a regular usb charger - 5v @ 500-2000mah, if you stick asus transformer cable it will switch to 15v @ 1200mah
asus cable sport a usb 3 connector but uses it in an non-standard way, pin 7 is used to switch modes, if the charger find it connected it will go into 15v mode otherwise usb mode.
on the other side, the tablet wont go into "charging mode" if it dont find at least 12v on its connector so if you want to build a diy charger you'll need one that at least has these specs.

It might work but you will most likely damage your motherboard. Sucking more out than what is supplied will destroy it. Hence why FC mods are not highly recommended. Look at the specs of whichever computer you are going to plug that into. If it has sufficient power (most are standard 5v 500ma) USB ports. Just use caution. I personally just grabbed a powered USB charger. Meaning, there is a battery that can be recharged from a wall outlet, the charged battery then charges whatever i plug into the two USB ports. (up to 15volts) works great on my TF300T. However, i hardly need to use it. Battery lasts all day from a single charge overnight from the wall outlet.

The QC 2.0 spec can use higher than 5v and as much as 3A.

Several 2a and 3a chargers on ebay and amazon for less than $15. Works fine when I use a generic 3a charger since the phone will scale power on need and availability.

I ended up buying the original charger linked in my first post. Will report back.

Isn't the quick charging a factor of voltage as well as amperage? Simply buying a 2am charger won't get you the built in quick charging if you don't have the voltage to back it up..

You are correct.

Ok I got the charger. While I have installed it, I haven't had time to test it fully.
When connected, it does display the Adaptive Charger Connected message.
How it differs from the Samsung home charger, it adds 12V to the mix
Charging at 5V is 10W, 9V is 14.4W, and 12V is 14.4W. (As is labeled. I haven't measured)

Depends on scale. It's more about the supply at the end really. From a car charger your converting 12v (supply limit amp) to 5v 5a or 12v 2a easy. Since its DC to DC stepping is fairly straight forward. The phone will never hit the amp limit in a car. Unless you drive a soap box. Smart chargers are like having mutiple chargers in the same device. It detects what's being asked and delivering accordingly. Much like pressing your thumb on a water hose and watching the water shoot out further.
As a side note just to be sure anyone isn't thinking about upping the voltage on a charger DONT. It doesn't work that way lol. Do a quick Google search on voltage conversion and you will understand how electrical supply can change.

The Powermod charger charges my phone in the car at least as fast as the OEM Samsung charger.... Highly recommended.

not all usb cable are the same !
not all usb cable will shows "adaptive fast charger connected" when connected to phone.
i have bought IXCC microusb cable 5 packs from Amazon,
i tested all 5 microusb cable, it DOES show "adaptive fast charger conncted" when connected.
5 packs = 9.99$
3 packs = 7.99$.

Got the Powermod permanently installed behind the dash in my car. Charging rate is fantastic.

I'm using this car charger with a rocketfish usb cable before I hard wire a solution...

Charges VERY quickly... in line with Quick Charge 2.0 claims...

I am starting to think the Powermod car charger wasn't all that fast.
I have replaced it with this one. The charge percentage goes up VERY quickly on this one.

When u say permanently, what do u mean? Some kind of customization or you just leave it there?

It's plugged into a 12v hub that I hardwired to the car's electrical system. I hid the hub behind the dash and then ran the charging cable up through the middle of my dash panels. It is perfectly positioned and comes out of the dash directly where my phone mount is located. I had to disassemble my dash to do it. Wasn't a big deal for me, as I already had my dash apart to flush mount my Nexus 7 as a "detachable" head unit for my sound system.

Does this do Fast Charge like the ac outlet ?
Thanks

That one isn't a QuickCharge 2.0 charger and is likely not as fast.
